In the stretching apparatus described in the publication, a total of six cylindrical roll bodies are rotatably arranged along one rotation axis which is curved in an arc over the entire width of the material web. . The axis of rotation is curved so that the outer roll body guides the material web with a slightly outward motion component, so that the material web is unrolled, thereby eliminating wrinkles present in the material web.

向きの度合が漸増することに起因している。The drawing device known from EP 0 470 332 also has a number of cylindrical rotary bodies in parallel along one axis of rotation extending over the entire width of the material web. Again, the stretching effect is due to the gradual increase in the outward degree of the roll with increasing distance from the midpoint of the material web.

Disadvantageously requires a high tensile force. In addition, the outward motion component of the roll body causes a slip between the roll body and the material web, thereby requiring a large contact surface between the material web and the tentering roll. Because
The material web has an adverse effect.

置の構造が著しく単純であるので、その製造費は格別低
廉になる。The stretching apparatus operates according to a principle different from that of a conventional stretching apparatus. The material web contacts the larger diameter side of both rolls outside the center. As a result, the material web is evenly guided over the entire width from both edges while rotating on the tentering roll, and is smoothly and flatly separated from the tentering roll. The stretching device of the invention therefore exerts a stretching force in the transverse direction over the entire width of the material web. Since only two roll bodies are provided in total, only two rolling bearings per roll body are required to support both roll bodies on their axis of rotation, so that the roll bodies are only slightly reduced by the material web. It can rotate with frictional resistance. Since the structure of the stretching device is extremely simple, the manufacturing cost is particularly low.

すことが可能になる。[0008] In an advantageous configuration of the invention, the roll axis of rotation is one-half of the cone angle of the roll so that one flat straight line is created at one location on the surface of the tentering roll. When extending outwardly at an angle, the material web diverted and guided by the tentering roll is:
Since it is oriented horizontally and completely flat, the material web can be post-processed immediately after release from the tentering roll.

Although the possibility of adjusting the winding angle of the material web on the tentering roll is ignored, the diameter of the tentering roll can be changed to further optimize the tentering action.

態で延伸装置から水平方向に離脱する。As can be seen from FIG. 1, the stretching apparatus has two rolls 1 and 2, both of which are rotatably arranged about one rotation axis 3 and 4, respectively. Together, they form one tentering roll. The two rotation axes 3, 4 are each inclined toward the outside of the stretching device. Accordingly, the two rotation axes 3 and 4 form an obtuse angle with each other in the central region. In order to support the roll bodies 1 and 2, two rolling bearings 5 and 6 along the respective rotation axes 3 and 4 are used. Thereby, the roll bodies 1 and 2 are rotatable along the respective rotation axes 3 and 4. FIG. 1
As can be seen, both rolls 1 and 2 are formed in a frusto-conical shape and are each tapered from the outside to the center of the stretching device. The inclination of both rotation axes 3 and 4 is
Since the outer peripheral surfaces of the two rolls 1 and 2 are selected so as to be located on one straight line on the upper side, the material web 7 that is deflected and guided by the two rolls 1 and 2 is stretched in a state of being extended. Separate horizontally from the device.

じて、多かれ少なかれ変化される。The stretching action on both sides of the material web 7 increases as the degree of winding of the material web 7 around the rolls 1 and 2 increases. This degree of winding can be changed by the adjusting device 8 shown in FIG. The adjusting device 8 includes a swing arm 9 supported on the rotation axis of the roll body 1.
The swing arm 9 supports a roll 10 at its free end, and the degree of winding of the material web 7 on the roll body 1 via the roll 10 depends on the position of the swing arm 9. , More or less changed.

FIG. 4 shows other diameters indicated by dotted lines except for the minimum diameter 2 ″ ′ and the maximum diameter of the roll body 2 as indicated by solid lines, and the center points M2 and M corresponding to the diameters.
2 ', M2 "and M2"' are shown. For both 90 ° and 60 ° winding, a plurality of parallel horizontal lines are shown by dotted lines. As can be seen from the drawing, the first point of contact between the roll body 2 and the material web 7 in each case moves upward as viewed from the outside to the inside. Correspondingly, the slope of the contact line, also shown for the case of a wrap angle of 90 ° and 60 °, becomes steeper with increasing wrap angle.
